In 1985, Mick Jagger and David Bowie recorded a version of the Martha and the Vandellas' 1964 hit "Dancing in the Street" for Live Aid.
The plan was for them to perform the song there with Jagger in Philadelphia and Bowie in London, but the satellite delay made that impossible. But, the video they cut for the song was shown twice during the all-day global concert.
Now, 29 years later, someone has had a little fun and removed the music from the video in order for us to "hear" what was really going on, including all of their supposed grunts and groans and a few other bodily functions.
